[Mirror] Announcing timeout for `mirrors.ft.uam.es`

After looking for this information for a while I didn't locate a specific channel to notify scheduled mirror downtimes to anybody...

In lack of a better medium, I wanted to drop a short message notifying the `mirrors.ft.uam.es` mirror will be unavailable starting 2023-04-21T09:00+02:00 and ending at 2023-04-24T21:00+02:00. We will be carrying out the maintenance of our infrastructure's power supply and will therefore be made to shut everything down.

If I should direct this announcement somewhere else please be sure to let me know.

Thanks a ton for your time and sorry for the noise,

Pablo Collado Soto
